当我尝试编译我的代码时，它会抛出66个错误，所有错误只是from copy import deepcopy
from typing import TypeVar
Cls = TypeVar('Cls')
# This type hint is a dirty lie to make autocomplete and static
# analyzers give more useful results. Crazy the stuff you can do
# with python...
def copy_class(cls: Cls) -> Cls:
copy_cls = type(f'{cls.__name__}Copy', cls.__bases__, dict(cls.__dict__))
for name, attr in cls.__dict__.items():
try:
hash(attr)
except TypeError:
# Assume lack of __hash__ implies mutability. This is NOT
# a bullet proof assumption but good in many cases.
setattr(copy_cls, name, deepcopy(attr))
return copy_cls
def test_copy_class():
class A(object):
mutable_class_var = []
ACopy = copy_class(A)
a = A()
acopy = ACopy()
acopy.mutable_class_var.append(1)
assert a.mutable_class_var == []
assert A.mutable_class_var == []
assert ACopy.mutable_class_var == [1]
assert acopy.mutable_class_var == [1]
个错误（重复行）。我尝试了Include guards，mat4.h。
代码
mat4.h
#pragma oncemat4.cpp 文件太大所以我会把它贴在pastebin上。 https://pastebin.com/FYSZV9ZX
答案 0 :(得分：0)
你的vec3和vec4标题是否包括mat4？
如果是，则没有必要，然后删除包含。
